Is there a more common plant in the Four Corners area? Yarrow’s fern-like leaves, which have a strong, pleasant, distinctive smell, often carpet meadows and woods.  Of these masses of plants, few produce flowers, but because Yarrow is so prolific there are still many flowers.  A close look at the flower often surprises, for it shows Yarrow to be a Sunflower with both ray and disk flowers. (See below.)  The dried flowers are long-lasting and are often gathered for household displays.

The Achillea genus was named by Linnaeus in 1753 when he also named this species "Achillea millefolium"from specimens collected in Europe.  Thomas Nuttall named this species "Achillea lanulosa" in 1834 from specimens collected by Meriwether Lewis in Idaho in about 1806.  Weber states that A. lanulosa and A. millefolium are "very closely related" but different species.

Achilles is believed to have discovered the medicinal uses of this plant for healing wounds.  "Lanulosa" is Latin for "wooly".

Beauty can be found in bud as well as in flower.

Yarrow spreads from stout roots and large patches of the fern-like basal leaves are a very common sight around mountain homes, meadows, and woodlands.
